Title: Method of and apparatus for weaving fabrics having a selvedge formed by folding in weft thread ends
IPC: D03D47/40
Filed: 1959-06-25
Abstract: 870,693. Forming selvedges; shuttleless looms; gripper shuttle looms. SULZER FRERES S. A. June 25, 1959 [June 27, 1958], No. 21901/59. Class 142(2) Half (or other fraction) of the picks of weft inserted by a gripper shuttle or by a positivelyoperated gripper have their leading ends coinciding with the edge of the fabric and the intervening picks are taken beyond the edge and tucked into the next shed to form a selvedge. Operating gripper shuttles. When a gripper shuttle 22 arrives in the catching device 26 and is arrested by a brake 27, a cam-operated pusher 29 moves towards the shuttle, whereby a resilient arm 37 snaps into a notch 39. The pusher moves the shuttle different amounts on alternate picks so that the ends of alternate picks coincide with or project from the edge of the fabric; after the gripper jaws have been opened to release the weft, the pusher draws the shuttle completely into the catching device, out of which it is pushed sideways, the notch 39 allowing this to occur without the necessity of raising the arm 37. Instead of pushing the shuttle back to position the weft ends, it may be arrested in the required positions by controlling the pressure applied by the brake 27, which may be supplemented by a transversely movable stop having two abutment surfaces. Positively-operated grippers. In the case of a gripper mounted on a rod actuated by a camoperated pivoted arm, the radius at which the cam acts on the arm is varied by linkage operated by an additional cam so that the stroke is altered, although it always starts from the same point at the entry side of the shed. Alternatively, the stroke may be kept constant but the pivot of the arm moved bodily so that the gripper arrives at different points at the exit side of the shed.

Abstract: 1,037,486. Making longitudinally reamed tubing; welding by pressure. KOCHS WERMELSKIRCHEN G.m.b.H., [trading as FRIEDRICH KOCHS]. June 4, 1963 [June 4, 1962 (2)], No. 22188/63. Headings B3A and B3R. A method for the continuous manufacture of welded metal tubes from metal strip comprises the steps of forming the strip into an open tube, bringing the edges of the strip together to weld same by induced heat, resistance heating the closed tube, calibrating the tube in the hot state and then cutting the tube into desired lengths. Strip 12 is formed by rollers 3 into tubing the longitudinal seam of which is induction welded by means 4 working at, for example 1-10 or 400 kc. and including an inductor 6 with or without a magnetic core. The tube is then resistance heated by means 7 which may include rollers or other contacts or inductors supplied with current. The hot tube then passes to a calibrating rolling mill 9, the rolls of which may be driven faster than the rollers 3 to stretch the tube between the means 7 and mill 9. The tube 13 is then cut off by a saw or shear 11. A motor 14 driving the rollers 3 and a motor 15 driving the rolls of the mill 9 may be controlled by means 18 measuring the thickness of the strip, and by means measuring the tractive pull on the tube and comprising detectors 16, 17 of the speeds of rotation of the motors or a device for measuring the torque of the motor 15. The mill 9 may be driven through a Ward-Leonard set. The thickness of the tube may be measured at 20. The intensity of the heating current to the device may be controlled rather than the tractive pull. Hydraulic drives may be used.
